    40 <para>The <filename class="directory">/dev/shm</filename> mount point
    41 for <systemitem class="filesystem">tmpfs</systemitem> is included to

    44 section). Please note that very little software currently uses
    45 POSIX-shared memory.  Therefore, consider the <filename
    46 class="directory">/dev/shm</filename> mount point optional. For more

    57 <para>This option will only work if <quote>Support for Host-side USB</quote> and
    58 <quote>USB device filesystem</quote> are configured in the kernel. If
    59 <quote>Support for Host-side USB</quote> is compiled as a module, then
    60 <filename>usbcore</filename> must be listed in
    61 <filename>/etc/sysconfig/modules</filename>.</para>
     62  <para>This option will only work if <quote>Support for Host-side USB</quote>
     63  and <quote>USB device filesystem</quote> are configured in the kernel. If
     64  <quote>Support for Host-side USB</quote> is compiled as a module, then
     65  <filename>usbcore</filename> must be listed in
     66  <filename>/etc/sysconfig/modules</filename>.</para>
     67
     68  <para>Filesystems with MS-DOS or Windows origin (i.e.: vfat, ntfs, smbfs, cifs,
     69  iso9660, udf) need the <quote>iocharset</quote> mount option in order for
     70  non-ASCII characters in file names to be interpreted properly. The value
     71  of this option should be the same as the character set of your locale,
     72  adjusted in such a way that the kernel understands it. This works if the
     73  relevant character set definition (found under File systems -&gt;
     74  Native Language Support) has been compiled into the kernel
     75  or built as a module. The <quote>codepage</quote> option is also needed for
     76  vfat and smbfs filesystems. It
     77  should be set to the codepage number used under MS-DOS in your country. E.g.,
     78  in order to mount USB flash drives, a ru_RU.KOI8-R user would need the
     79  following line in <filename>/etc/fstab</filename>:</para>
     80
     81<screen>/dev/sda1    /media/flash vfat noauto,user,quiet,showexec,iocharset=koi8r,codepage=866 0 0</screen>
     82
     83  <para>The corresponding line for ru_RU.UTF-8 users is:</para>
     84
     85<screen>/dev/sda1    /media/flash vfat noauto,user,quiet,showexec,iocharset=utf8,codepage=866 0 0</screen>
     86
     87  <note><para>In the latter case, the kernel emits the following message:</para>
     88
     89<screen><computeroutput>FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!</computeroutput></screen>
     90
     91  <para>This negative recommendation should be ignored, since all other values
     92  of the <quote>iocharset</quote> option result in wrong display of filenames in
     93  UTF-8 locales.</para></note>
     94
     95  <para>It is also possible to specify default codepage and iocharset values for
     96  some filesystems during kernel configuration. The relevant parameters
     97  are named
     98  <quote>Default NLS Option</quote> (CONFIG_NLS_DEFAULT),
     99  <quote>Default Remote NLS Option</quote> (CONFIG_SMB_NLS_DEFAULT),
     100  <quote>Default codepage for FAT</quote> (CONFIG_FAT_DEFAULT_CODEPAGE), and
     101  <quote>Default iocharset for FAT</quote> (CONFIG_FAT_DEFAULT_IOCHARSET).
     102  There is no way to specify these settings for the
     103  ntfs filesystem at kernel compilation time.</para>
     104  <!-- Personally, I find it more foolproof to always specify the iocharset and
     105  codepage in /etc/fstab for MS-based filesystems - Alexander E. Patrakov -->
